Be it known that I HENRY KLECKLER a citizen. of the United States,residing` at Buffalo, in the county of Erie and State of New i 'Yorinhave invented certain new and useful 5 Improvements in Tail -Skid Clips,of which the following iea specification. My linvention relates tottings for aeroplanes. The characteristic of this invention is set forthin an application tiled January 13, l9i6, Serial No. 71,892, '0f-Whichthis ap-v As thereinv pointed out it is the aim and purpose or theinvention-to simplify and improve the dctailsfof construction of lminoraeroplane parts. j

The particular l'ittting-'or aeroplane part comprehended by theinvention is the litting referred `to in theoriginal application as thetail `skid clip. The construction of the clip is Such that the tail skidis not onlyfastened tothe aeroplane body thereotmay be eil-ecte'd inrectangularly opposed planes. This movement is. especially shocksincurred through side swipe incident to landing or to travel over roughor uneven ground. Moreover. the clip parts are interrelated and arrangedfor extreme compactness and assembly in the construction of a machine.

0f the drawings, wherein like characters of reference designate like orcorresponding parts; y

Figure l is a side elevation of the tail skid clip; v

Fig. 2 is a section teken on a vertical through the center of the clip,and

'Fig'. 3 is a section. taken on ahorizontal plane through the socketmember oi the clip.

For thc purpose of illustrating the application oi the invention the.socketl member ot' the clip? designated lin its entirety by the numerall0. is shown as attached to the extended terminal ot the stern post ofthe ituselage or body of an aeroplane (not shown). The fastening meansfor thesoclet member consists of bolts 12 and 13 passing transverseljvthrough the stern post 1i in intersecting planes, the bolts 12conjointly iunctioninp; as a securing' means for diagonally extendingtubular braces 14 and the bolt 13 as a securing' means for the stay 15gthe braces 14 and the stay l5 lilreivise extending intersecting Vrdimes.For the convenient plane 1917.

The tailfslridor sltid'bar li( (herein but Apartly shown) is lnountedfor pivotal movement in rectenguiarly opposed planes, the'y skid beingfastened at its forward eleva'ted end by any suitable elastic means toInterino the fuselage or bodf,7 of the craft.

These lates i9 and 20 are providedwith alined oies .through which the pivot pin or bolt 2i (Fig. 2)`extends. A recess 22. is formed in the stern post ll at its base tofreceive that portion-of tlie bolt 21 penetrating the socket member 1.0and exe 'tending upwardly therebeyondl The nut 23 for securing .the bolt21 in place is also inclosed Within this recess.

A,'llhe fastening means for the tail sind l? also comprises a pivot pinor bolt 2li. This as illustrated overlap and receive between 'them theretaining` plate 26 and a portion 'of the'slzid bar to which said plateQG is somewhat elonto the top surface ot the skid/17. intermediatelysaid plate is oti'set to provide in effect' coniplcinental to acts asthe skid bar fasteningmeans Without` penetrating' orpiccing the skid.Ears 25,' down-turned yin Figgg.I 2,4 are formed upon the plate @to 26is rigidly secured underneath surface oat the plate soV lOl.

El as pivot airis about which the bar :may be moved in a vertical plane.A strong sub stentieliy eluniversal mounting of this iinproved .in elsgeadjunct is thus evolved. The plates i9 end 2G take np tbe friction andweer in `ident to lateral displacement ei' the skid bor n Furthermore,quick bly in the cinstruction or' an aeroplane is made possible by theinteri-relation and'cordination oli these extremely simple clip parte.The pivot pinJ 21 being partly incloscd, it is, head resistancey duringflight through the ein is reduced.

Although the socket member l@ is shown as fastened to the stern post ll,no limita tion in this respect is intended. The socket member may befastened to any rigid ele nient of the aeroplane body. Furthermore, theconstruction of the retaining plate and bearing member may be altered.Such modifications and changes are clearly4 Within the Spirit of theinvention claimed and mey be found essential in the adaptation of theclip to aeroplane bodies oi different design.

lWhat is claimed is:

l.. A tail skid clin or aeroplenes including an element rigidlyconnected with the body of the craft, the underneath snriaace of seidelement alici-ding a lined bearingf surfsce 'of substantial size amovable member havingn a ton surface similarlv formed and engagementwith the bearing surface of said element, a loose connection betweensaid element and said membri", the connection being such that thesurfaces are held in engagement with each other. and a loose connectionbet-Ween the movable member and the skid.

2. A tail skid clip for seronlanes including a socket member having; itsonder face constructed to provide a, bearing surface a securing 4platefor the tail skid having its top 'face constructed' to provide s bearingsurface.l surfaces being substantially complemental and in abuttingengagement, a connection between said socket member and said plate, anda connection between said plate and said skido 3. i tail skid. clip foraeroplenes including-#ay fixed bearing member constructed in socketforen the underneath surface of member constituting e bearing snr-tace,and a relativelyl movable bearing member havingI connection with Athetail skid. said movable bearing member being likewise provided withbearing surtace for Contact with the bearing surface of the iXed bearingmember of the clip.

4. A tail skid clip 'for aeroplanes including an apertured bearingmember rigidly connected with an element ot the bodv olf the craft, anapertured movable bearing" inemA ber mounted for Contact willi said rigid been one ing member, the relative positioning of the plates beingsuch that the apertures coincide,

Aa pivotal connection between the respective members, connecting meansextending through said apertures, and `a pivotal coinieetion between themovable bearing member and the tail. skid, the pivotal connectionstogether providing a means Where by said tail skid may be moved indifferent planes.

5.
